The famous German VDE FNN Steuerbox (Control Box) Version 1.5 is now available as English Version (edition August 2026).
"The "Specification for Control Box: Functional and constructive properties" describes one option for implementing control via smart metering systems. With this new version, VDE FNN has made important corrections regarding the operation, application, and compliance of the Control Box. Among other things, the parameter set and certificate set were updated, and corrections were made to the [added by editor: IEC 61850] data model. These new adjustments thus improve the operation and flexibility of the FNN Control Box and make an important contribution to implementing control via the smart metering system."
